Couldn't say thunder, I haven't researched MRX other than its no longer listed. The area as I mentioned is around Mt Dorothy in Queensland.
Matrix metals has four tenements in the area within 10-15kms that I found so far , EPM 14138,15859,17910 and EPM17904.
Known REE in the area might increase their value if Matrix can find a purchaser, if they haven't been sold already. Although Matrix is still shown as the owner on the Qld mines website.
